Detailed Description

A very simple extended HashMap, which maintains order via an ArrayList.

This class provides similar, though not identical, functionality as the JDK's LinkedHashMap, but works under JDK 1.2 and JDK 1.3.

This class is not synchronized, if more than one thread accesses an instance of this class and at least one thread modifies the map, the OrderedHashMap instance must be synchronized via a call to Collections.synchronizedMap method.

The entrySet() and keySet() methods return unmodifiable sets.

The values() method returns an unmodifiable collection.
